There are basically two types of weathering that affect the rocks of the Earth, those are mechanical weathering and chemical weathering.  Mechanical weathering is a physical process that breaks the rocks down into smaller pieces, such as the affects of wind, water, and temperature.  Chemical weathering is an actual chemical process that can change the minerals and chemical content of the rocks involved, so judging from your question stem, I would tend to say this sounds like chemical weathering.

Creep, one of the other choices, is what the Earth does when it is on a sloping hillside, and due to erosion or weathering factors, the hill slowly "melts" down the slope.  Mass wasting, the other choice, is another erosional choice that refers to entire volumes of land that have been removed as a result of erosional forces.  Erosion is one of the major forces that tends to cause wear and tear on Earth's surface.
